in-fthe 'c'ounty'of Cook and State of lhinois,

'have invented acertain new and usefullfm-n 'provement in Magnetic Separatore, of which the following is a full, clear, concise, and erract description. i e

' My invention relates Vto ainagnetic oreseparator for the concentration oi" ores in a vwet-condition; "and its object is to provide improved simpleapparatu's whereby a mix- Ag ture of magnetic and ncinrnagiietic materials may be treated in such a way that -the magnetic' material will be taken out and the re- "mainder ol' the material classified or concentrated according to its specific gravity; all in the saine operzrtion.-v i The invention relates more particularly to the class oi concentrators known as buddles and contemplates an improved buddle in which means are 'provided tor concenrest. 1

` z I'will describe myinvention particularly by trating the magnetic material apart from the reference to the accompanying drawings, and they parts," improvements, or 4combinations i which I regard as novel will be pointed out in the appended claims.

In the drawings, Figure l is avertical sec- Itional elevation of my 'ore-concentrator. fFig. 2 is `a plan view thereoi with parts "ture is built up.-

cone lor receiving the material washed down.

A conical ma metio armature d' is arranged to rotate ironie iately above the cone a and in close'proximity thereto, and magnets e e are provided at Iintervals around the circumference of said armature, with o posing poles N S above said armature and be ow said 4cone e, respectively, so that the material passing down the surface of the cone will traverse the intense magnetic flux whichV passes from pole to pole of each magnet through said armature. is intended that the armature in its rotation shall piek up the more permeable particles of ore or material passin clown said conical feedu surface and trans 'er the same to the extreme edge of the magnetic Jfield established between the poles N S of 4each magnet, and the armature is therefore provided with lineans for securingdispersions or divergences of the magnetic lines of force from its under surface. in magnetic attraction the movement oi the particles is along converging lines of l'orce.

ridges, or projections on its under surface the more permeable particles will tend to adnations are preferably assembled in relative4 positions to present the teeth in staggered rows. it will rbe seen that this laminated construction lends itself readily to the production of divergences or dispersione of the magnetic flux, .not only because of the ease with which a toothed surface may be built up of serrated plates, but also because lines oi: force naturally tend to diverge from the edges ofthe individual plates.. It isevident that any desired formy of teeth, ridges, or permeable proj ections maybe provided, and it is not necessary that the `'physical surface of the armature should be roughg-Ip Therefore if the l .armature is provided with magnetic teeth;

tion of said. table, .means for directing the Apassage of material radially down said table 1n dil erent directions, a series of magnets having poles adjacent to said table near the respective paths of such material, a conical annulararmature arranged to rotate above said table, and means for collecting the material at different points around the lower edge of said table.

3. In a magnetic separator, the combina-` terial to be separated between the laminated surface of sai armature and one 4of said inagrelatively rotated, and means for passing manet-poles.

4. ln an ore-concentrator, the combination with a rotating conical Atable and means for feeding material to be separated to the upper part thereof, means for supplying water to said table to wash down the materials, the lighter material being thus discharged from the table at a different oint from the heavier material, magnetfpollds of op osite polarity arranged above and below sa1 table and a conical annular armature arranged to rotate above said table, between said magnet- 3o poles; whereby the magnetic material is defieeted into a path different from the remain- -gassage of material radially down sai taf le in diiierent directions, a series of magnets having poles adjacent to said table near the respective paths of such material, a conical annular armatureabove said table, said table and armature being mounted to rotate in opposite directions, yand means for collecting the material at different points around the lower edge of the table.

6. In-a magnetic separator, the combination with -an annular table 'adapted to cause the passa'e of material, fed centrally there-- on, radial ble, of a magnet above said table and an annular armature concentric with the table and y toward the outer edge of said taarranged to rotate above said table in an airgap between said magnet and table.
